In contrast, the area other than the standby area AR$7 on the display screen H (hereinafter referred to as the page data display area) ARmp
When the pen is raised within the window, the window W is moved to the position where the pen is raised.

Therefore, when storing the window W, the user has to repeat the troublesome task of moving the pen to the standby area ARsy each time, and there is still a problem in terms of usability.

One way to solve this problem is to increase the size of the standby area A Rs'r, but if the standby area A Rs'r is made thicker (then the display area AR can only be displayed in a small display area.

(Gl-2) Window storage In this embodiment, the central processing unit 24 executes the processing procedure shown in FIG. 1 with the window W displayed, thereby moving the window W and moving the window W as necessary. and stores the window W.

That is, the central processing unit 24 moves from step SP1 to step SP2, and detects the coordinate data of the pen 6 by taking in the coordinate data from the tablet interface circuit 31.

Subsequently, the central processing unit 24 moves to step SP3 and determines whether or not the pen 6 has been moved down based on the output data of the tablet interface circuit 31.

If a negative result is obtained here, the central processing unit 24 returns to step SP2, thereby repeating the loop of steps 5P2-3P3-3P2 until the pen 6 is brought down.

On the other hand, when pen 6 is brought down, step S
When a positive result is obtained in P3, the process moves to step SP4, and after clearing the counter, step SP
5, the current time t is fetched from the timer 35 and the current time is recorded.

Subsequently, the central processing unit 24 moves to step SP6, and records the coordinate data X and y taken in in step SP2 as coordinate data of count value n-0.

Subsequently, the central processing unit 24 moves to step SP7, increments the count value of the counter, thereby updating the count value n, and moves to step SP8.

Here, the central processing unit 24 takes in the coordinate data from the tablet interface circuit 31, and thereby
After taking in the coordinate data of the count value n (in this case, n-=l), the process moves to step SP9, and it is determined whether or not the pen has been raised.

If a negative result is obtained here, the central processing unit 24
Returning to step SP6, the loop of steps 5P6-3P7-3P8-3P9-3P6 is repeated until the pen is up, and as the count value n increases, the coordinate data x0, 'Io, X+, and yI
%''..., and thereby the trajectory of the pen 6 can be detected based on the coordinate data Xll, FO1χ1, yl,....

On the other hand, when the pen is up, an affirmative result is obtained in step SP9, so the central processing unit 24 moves to step 5PIO, clears the counter to the value 0, and then moves to step 5P11.

Here, the central processing unit 24 stores the y-direction coordinate data y when the pen is raised in the register, and then the y-direction coordinate data y0 of the cleared count value 0 is larger than the coordinate data y in the register. Decide whether or not.

If a negative result is obtained here, the central processing unit 24 moves to step 5P12, and after up-counting the count value, determines whether the up-count value i is smaller than the count value n at the time when the pen is raised. to judge.

If a positive result is obtained here, the central processing unit 24 returns to step 5PII, and calculates the y-direction coordinate data y of the up-counted count value i.

It is determined whether the coordinate data y in the register is larger than the coordinate data y in the register.

(As shown in FIG. 4, if the pen 6 is moved monotonically to the negative side in the y direction and then moved up at point Pz after the pen is brought down to point P0, negative results are obtained one after another in step SpH. As a result, the central processing unit 24 performs steps 5P11-3P12-SP13-3PI 1
Repeat the loop.

In this case, at point P7 immediately before point Pt, step 5P
Since a negative result is obtained in step 13, the central processing unit 24 executes step 5P1 while keeping the coordinate data in the register at the coordinate data y of the pen-up point P2.
Move on to 4.

Thereby, the central processing unit 24 sequentially detects the trajectory of the pen 6 and holds the most negative coordinate data y in the register.

On the other hand, as shown in FIG. 5, if the pen 6 is moved down to point P, then moved monotonically to the positive side in the y direction, and then raised up at point Pt, the coordinate data y0 of point P, By obtaining a positive result in 5PII,
The central processing unit 24 moves to step 5P15.

Here, the central processing unit 24 sets the coordinate data y in the register to the coordinate data of the count value (in this case, the coordinate data y of the pen-down point), and then moves to step 5P12.

As a result, the central processing unit 24 updates the coordinate data in the register, and then performs step 5PII-3P 12-
The loop of 3P 13-3P 11 is repeated, and in the same way as when the pen 6 is moved monotonically to the negative side, the locus of the pen 6 is sequentially detected, the coordinate data of the most negative side is held in the register, and step 5PI4 Move to.

Similarly, as shown in FIG. 6, if the pen 6 is moved down to point 11 P, monotonically moved to the positive side in the y direction, turned back at point P, 1, and brought up at point P2, step sp.
The loop of i 1-3P12-3P13-3pH is repeated, and while the coordinate data y in the register is held at the coordinate data of the pen-up point P, step 5P14
Then, the most negative coordinate data y is held in the register.

On the other hand, as shown in FIG. 7, after moving the pen 6 down to point P, the pen 6 is moved monotonically to the negative side in the y direction to point P,
If you turn around at point P0 and pen up at point P0, go from point P0 to point P. In the interval up to, step SPI 1-
A loop of 3P15-5P12-3P13-5PII is repeated, thereby sequentially updating the coordinate data in the register to the coordinate data Yi of the count value i.

Furthermore, in the section from point P to point P, the loop of steps SPI 1-3P12-3P13-3P11 is repeated, and as a result, the coordinate data Yi of the turned point P is held in the register, and the step 5P1
Move on to 4.

Thus, in the central processing unit 24, the pens 6
, and the most negative coordinate data is stored in a register.

In step 5P14, the central processing unit 24:
Regarding point P1 of coordinate data y stored in the register,
It is determined whether the pen down point P is located sufficiently on the negative side in the y direction.

This judgment is made based on whether the coordinate data stored in the register satisfies the following relational expression % (1) for y, and if a negative result is obtained, the central processing unit 24 is step 5P
After moving to step 16 and moving the window W to the pen-up point P2, the process moves to step 5P17 to end the processing procedure.

As a result, as described above with respect to FIGS. 4 and 5,
If the pen 6 is moved monotonically, a negative result is obtained in step 5P14, and the process of moving the window W is executed.

Also as described above with respect to FIG. 6, point P.

If the pen 6 is moved monotonically to the positive side in the y direction and turned back at point Pw, and the pen is raised at point P2, then the pen is raised at the point P! Since the coordinate data of is held in the register, a negative result is obtained in step 5P14, and the process of moving the window W is executed.

On the other hand, as described above with reference to FIG. By holding the coordinate data of the point PM in the register, an affirmative result is obtained in step 5P14, and the central processing unit 24 moves to step 5P1B.

Here, the central processing unit 24 sequentially executes the following processing steps to store the window W, and thereby stores the window W simply by moving the pen 6 in a bouncing manner.

Therefore, without repeating the complicated work of moving the pen 6 to the standby area A as in the past, the window W can be stored by simply flipping the pen down, simplifying the window storage operation. can be used to improve usability.

In reality, the action of bouncing the pen 6 is
Compared to the operation of moving the window W to the standby area ARsy, this operation is adapted to the feeling that the user wants to erase the window W from the display screen.

Therefore, by storing the window W in this way, it not only simplifies the operation, but also improves the usability compared to the conventional method, which improves the usability of the information processing device L accordingly. can do.

Furthermore, since it is not necessary to display the standby area AR3T while the window W is being displayed, the display area A Re F of the page data can be enlarged by omitting the display of the standby area ARst, and the corresponding area The usability of the information processing device 1 can be improved.

By the way, a user who is not accustomed to operating the tablet 32 may cause the pen 6 to vibrate slightly when the pen is put down, and as a result, the trajectory of the pen 6 may be detected as being turned back.

In addition, there are cases where the pen is down when trying to store the window W, and then the user is deterred.

Furthermore, depending on the usage environment, the coordinate data may fluctuate due to noise.

Therefore, if window W is stored in such a case,
On the contrary, the usability of the information processing device 1 will be impaired.

Therefore, in step 5Pi8, the central processing unit 24 changes the pen-up point Pg to the pen-down point P0.
It is determined whether or not it is located sufficiently on the positive side.

This judgment is based on the coordinate data of the pen-up point P, yU
P, it is judged whether or not the following relational expression is satisfied. If a negative result is obtained here, the process moves to step 5P16, and after moving the window W to the pen-up position, step 5P
The process moves to step 17 and ends the processing procedure.

As a result, the central processing unit 24 performs step 5P14.
and 5P18, when the distance between the points P, ,P, ,21 is less than a predetermined value, the window W is moved to the pen-up position, while the corresponding point P, ,P, ,Pt
When the distance between them is equal to or greater than a predetermined value, the process moves to the following step 5P19.

This prevents the window W from being stored even if the user accidentally lowers the pen and the trajectory of the pen wanders.

In step 5P19, the central processing unit 24
The following formula % formula % (3) Y = Σ (lyt F = - + haze ...... (4) im
1 is executed, and the moving distances X and Y of the pen 6 from when it is brought down to when it is brought up are detected.

Subsequently, the central processing unit 24 moves to step 5P20 to take in the current time tUp when the pen is up, and then moves to step SP21 to detect the time Δt from when the pen is put down until when it is brought up.

Next, the central processing unit 24 moves to step 5P22 and determines whether the time Δt from pen down to pen up is sufficient by determining whether the following formula % formula % (5) is satisfied. If a negative result is obtained here, the process moves to step 5P16.

Thereby, the central processing unit 24 is configured not to store the window W if, for example, the user accidentally puts down the pen and then quickly raises the pen.

On the other hand, if a positive result is obtained in step 5P22, the central processing unit 24 moves to step 5P23, and calculates the moving distances X and Y from the pen down to the pen up using the following formula % formula % (6) It is determined whether or not the following is satisfied, and from this it is determined whether or not the moving distance of the pen 6 is sufficient.

That is, in cases where the user has given up on storing the window W, the moving distance is considered to be short.

Therefore, if a negative result is obtained in step 5P23, the central processing unit 24 moves to step 5P16, moves the window W to the pen-up position without storing it, and then moves to step 5P17 to end the processing procedure. do.

On the other hand, if a positive result is obtained in step 5P23, the central processing unit 24 moves to step 5P24, executes the calculation process of the following equation, and detects the moving speed V of the pen 6 from when it is bent down until when it is raised. do.

Further, the central processing unit 24 determines whether or not the following relational expression (% formula %) is satisfied for the moving speed V. As a result, when the moving speed V of the pen 6 is slow, the process moves to step 5P16 and the window W After moving, the process moves to step 5P17 and ends the processing procedure.

On the other hand, if the moving speed V of the pen 6 is fast, an affirmative result is obtained in step 5P24, so the process moves to step 5P25, where the window W is stored, and then the process moves to step 5P17 to end the processing procedure.

That is, when the pen 6 is moved in a bouncing manner, it is generally considered that the moving speed V is fast.

Therefore, not only when the trajectory of the pen 6 is turned back,
In addition, by storing the window W based on the moving speed, the window W can be reliably stored when the user desires.
can be stored.

(Gl-3) Operation of the embodiment In the above configuration, when the key switches 4a to 4d and 1la to 1id are turned on in the information processing device 1, the operation mode is switched and desired personal information is displayed on the display panel. 5 will be displayed on the screen.

In this state, after moving the pen 6 down onto a desired icon, the pen 6 is moved to the page data display area ARDP, and a window W is displayed at the moved position.

In this state, after lowering the pen to a predetermined area ARN of the window W, if the pen 6 is moved in a large bouncing manner,
The central processing unit 24 performs step SP14-3P1B-
3P19-3P20-3P21-3P22-3P23-
By sequentially executing the processing steps 3P24-3P25-3P17, it is detected that the trajectory of the pen 6 has turned around significantly, and the window W is stored.

On the other hand, when the pen 6 is simply moved, the process of step 5P16 is executed and the land W is moved to the pen-up position.

(Gl-4) Effects of the Embodiment According to the above configuration, the processing mode is switched based on the trajectory of the pen 6, and when the trajectory of the pen 6 is largely turned back, the window W is stored, thereby eliminating the need for a complicated window. The work of storing W can be simplified, and the usability of the information processing device I can be improved accordingly.
